85 300SD... tranny issue. Throw in the Towel?

I'm seriously considering parking my 85 300SD. I know that I don't have much more than another year, two tops on the body due to rust in the front quarters.

However.. my transmission issue is as follows.

Large amount of fluid seems to be coming from the tranny. leaking on the garage floor. Hard to pinpoint where it's coming from. It started slipping on me. My indy guy told me to make sure it had plenty of fluid, and see if it still slips.

Fluid cured the slip.. but it won't hold the fluid. I can visually see the fluid coming out at stop signs. When I get on the brakes and the car tips forward a bit.. fluid POURS out.

It was acting like this for a few days. Before it would do it on corners. Fluid would pour from the tranny when I follow the curve in my driveway. I have some 200 foot plus long streaks in my driveway from ATF.

Thoughts?

Also.. my climate control died two days ago. no output at all. no blower, no AC no defrost, nothing. Fuse is fine.

Car has 238k.. and has been good to me. But I think I'm giving up.

Have you gotten under it and taken a look? Not unusual for a cooler line to fail. Little more unusual for it to start pouring out of somewhere else.

If you can see it pouring out I'd first check the transmission cooler lines.

nope

not way up front at the cooler line, it leaks out from the transmission itself, mostly dripping off near where the condensation comes from the AC

It doesn't leak much at all just sitting still, mostly just when the car is tipped due to braking, or when turning.

If it's coming through the "grate" where you can look up and see the torque converter, it could be the front seal or the pump seal. That's going to be terminal in your situation, if you can't live with it.

good news?

I got it up on jacks in the house.

I can't see ANY leaking above the pan gasket at all. I CAN see where the pan gasket was not installed correctly, and is pinched/off on the front right corner.

Would sloshing out of the pan be possible, and lead to low fluid in this case?

man, it would be nice if it was that simple. i'll deal with climate control after.

The cooler lines come from the transmission and can leak anywhere along their length depending on where they fail.

i would definitely change the pan gasket; it's very possible that's its leaking from that corner where the gasket is pinched (that would explain why it's leaking a lot when you brake or take corners since you said it's the right front corner (and the fact that there is no pressure inside the pan would also explain why it only leaks when braking or cornering) Changing the pan gasket is simple: i think there are only 6 bolts that hold the pan to the tranny; the gasket goes over the lip of the pan. drain the trans fluid first, i would also change the filter while you got the pan off. it will probably take about 4-5 quarts of transmission fluid if you only drain the pan (about 7-8 quarts if you drain the torque converter too)

hope this helps and report back if this was the problem

thanks,

shade
